You're leading a large group facilitation. How can you encourage insights from reserved colleagues?

There is no substitute for asking what they think. I invite them into the conversation individually. If it's a quiet group, having them do a conversation in pairs also gets people talking.

Setting the tone early on safe practices within the facilitation are key. I love icebreakers, and keep a few top of mind depending on what the scope of the facilitation is. As the meeting wears on, I try to notice what habits the reserved person falls back into (e.g. are they using their phone to "hide", do they gravitate to someone stronger), and then I'll work to establish a time for them to either work into that security item, or work to have them speak instead of relying on their stronger partner.

Communications are often assumed. As in we in a position of leadership assume we will be communicated with when necessary. But, good communication is earned. You need to identify those that are more reserved, and also, identify how they prefer to communicate. Some will not contribute in a large group setting, while still harboring a unique perspective. The communication must be pulled out at first, and encouraged, then it will begin to flow more naturally.

Considero que el facilitador debe generar confianza en el grupo , hay miembros más reservados, entonces contar quizá una anécdota personal, relacionada con la temática que está buscando que mencionen los participantes del taller o dinámica

Create an inclusive event based on collective intelligence means to consider how each people prefers to communicate. In my opinion the role of facilitators(s) is key : allow communication from all and preserve collective dynamic.

A variation on this that I like is to call on two quiet participants by name: e.g. What do others think? John, Sarah, do you have anything to add? This takes away from putting a shy individual on the spot.

The idea of a direct invite is wonderful. When I do this, I'll follow it up with a complement about them, such as, "When we were talking 1:1 you mentioned...", or "when you were talking within your small group, you had an idea that..."This helps give them some momentum, lets them know they are valued, and people notice them.

It is always worth paying attention with patience to everyone including people the reserved participants in groups may it be in moments they comment in the large group, the smaller groups or in the -maybe most important moments - in the breaks and walks to site visits.
